Jim's speedboat can travel 24 miles upstream against a 4 mph current. In the same amount of time it travels 26 miles

8_murik_8 [283]

Answer:

speed of the boat = 100 mph

Step-by-step explanation:

Let x = speed of the boat

upstream speed = x - 4

downstream speed = x + 4

time = 24/(x - 4) = 26/(x + 4)

Cross multiply:

24(x + 4) = 26(x - 4)

24x + 96 = 26x - 104

104 + 96 = 26x - 24x

200 = 2x

x = 100 mph

If you translate Point A ( 1 , 3 ) using the rule ( X , Y ) --> ( X + 2 , Y + 5 ) then A' coordinates

andrew-mc [135]

Answer:

A' (3, 8 )

Step-by-step explanation:

Applying the translation rule to A (1, 3 )

A (1, 3 ) → A' (1 + 2, 3 + 5 ) → A' (3, 8 )

A ramp has a horizontal distance of 10 feet and a vertical rise of 3 feet. Find the length of the ramp. Round to the nearest ten

Tatiana [17]

Answer:

Step-by-step explanation:

Tye length of the ramp can be gotten using Pythagoras theorem.

Horizontal distance = 10ft.

Vertical distance = 3ft

Length of the ramp² = 10²+3²

Length of the ramp² = 100+9

Length of the ramp² = 109

L² = 109

L =√109

L = 10.44ft

Hence the length of the ramp is 10.4ft to the nearest tenth

The percentage of water in an unknown hydrate was determined by heating the sample and driving the water off the sample. Two ind

Bas_tet [7]

Answer:

It should be reported as 20.648%

Step-by-step explanation:

Since we have 2 different observed values hence we shall use an average of the 2 values to report the result

Thus value is $\frac{19.564+21.731}{2}=20.6475%$

As we can see that the least count of our observations is upto 3 decimal places hence we have to report a result upto only 3 decimal places thus we need to round off the fourth decimal place thus the digit shall be increased by 1 since we have to drop off 5 and the digit before 5 is 7 which is an odd number.

Thus the result shall be 20.648%
